The SFM Series Solar Powered Intelligent Fuel Maintenance System is designed to optimize and maintain diesel fuel indefinitely by removing particulate and water in stored fuel. Powered by a solar panel, this innovative process stabilizes diesel and bio-fuels, eliminates microbial contamination, and ensures clean reliable fuel at all times. The SFM Series Solar Powered Intelligent Fuel Maintenance System is ideal for stored fuel in remote locations where power is not readily available.

Diesel Fuel is often the fuel source of choice in applications requiring generated power over wide geographic areas. Large farm operations need to power water pumps on short notice to provide water for irrigation and to fight damage from frost conditions. Often these pumps are in stand-by mode for extended periods. A fuel tank may sit in the sun and be subject to extreme temperature variances that cause the formation of condensation in tanks, providing the perfect habitat for microbial and fungal growth. Long periods when equipment remains idle allows for the infestation to develop and, when conditions demand the pump be ready to serve, the need is not met due to clogged filters and fuel that is in such a condition that prevents efficient operation of the diesel engines.

Other uses of the SFM Series Fuel Maintenance System could include:

  • Generators providing reserve or backup owner to cell phone towers.

  • Genrators providing water for pump water for live stock in remote grazing grounds

Remote monitoring services are widely available to tell you that your remote generator has failed to perform a test start up or is not operating when the need for reserve power arises, but that is of little help when the cause of the failure is contaminated fuel, clogged fuel filters, and mechanical failures caused by fuel that has gone bad. Maintaining fuel in optimal condition is necessary and is assured with the use of the AXI® Solar Powered SFM-1080.

Fuel has a limited shelf-life, and even "fresh fuel" could contain water, sediment, and microbes upon delivery. With the extreme conditions stored fuel is commonly enduring, it is critical to ensure fuel is maintained on a regular basis. SFM Systems reverse fuel deterioration while decontaminating, cleaning, and optimizing the fuel to ultra clean levels for ultimate reliability.

SFM Series Systems are designed around a self-priming 80 GPH nickel-plated brass gear pump. Quality filtration components are connected using corrosion-resistant Stainless Steel plumbing. A pressure gauge is installed on the filter housing to ensure optimal filter usage by showing remaining filter life. Available filter elements include a Primary stainless steel mesh filter, a Secondary spin-on filter element that may accommodate a 10 micron particulate, or a 3 micron water block elements.

SFM Series Features include:

  • Compact Industrial Lightweight Design

  • SMART Solar Controllers

  • Fully Automated Operation

  • Unique Safety & Alarm Features

  • Discreet Alarm Indicator Lights

  • Continuous-Duty Pumps, Viton Seals

  • NEMA Rated Weatherproof Enclosure

Principle Components

The principal components are a Helical Spur Gear Pump, a primary filter/screen, a secondary spin-on fine filter, an AXI Fuel Conditioner, and a SMART Solar Controller.

The fuel enters the fuel treatment system first through the LG-X 500 Fuel Conditioner that reverses the process of fuel breakdown, restores fuel filterability, enhances combustibility and prevents clogged filters and tank sludge. Optimizing fuel droplet size results in combustion efficiency, improved filterability and lower operating costs.

The primary filter/screen removes major contaminants and any items that may be in the fuel tank that would damage the fuel pump, such as foreign objects that may be introduced with fuel fills (such as screws or hard debris). The 50 mesh screen is cleanable and easily removed and replaced.

The secondary filter comes standard with a 3 micron Water Block spin-on filter element. Water Block elements will remove the emulsified water that becomes entrained in the fuel during the fuel fill-ups. As an alternative, a 10 micron fine filter particulate removal element is available.

A vacuum switch is positioned between the primary filter/screen and the pump to sense if the primary filter is clogged, thereby restricting the flow of fuel to the pump. A pressure switch is positioned between the pump and the secondary spin-on filter to sense if the pump is pushing fuel to a restricted or clogged secondary filter. Any excessive vacuum on the suction side of the pump, or excessive pressure on the pressure side of the pump will alert the controller to the need for filter maintenance and shut down the system to assure that the condition does not cause damage to components.

A float valve is installed in the base of the cabinet to sense if an accumulation of fuel may occur caused by a leak or other component failure, automatically stopping system operation.

The Solar Charge Controller and Solar Panel Battery Regulator will automatically manage the solar panel and battery, providing overloading and short-circuit protection, featuring reverse discharging and reverse-polarity protection, and under-voltage and over-charging protection.

The SMART Solar Controller includes a timer controller and sensors to shut down in the event of high vacuum, high pressure or leak detection.

The entire package is contained within a NEMA Rated Weatherproof Enclosure including locking hinged front door.

The Magnetic Fuel Conditioner

Operating on the principal of induction on the process of combining kinetic and magnetic energy to influence the behavior of electrons, the AXI Fuel Conditioner provides a powerful magnetic field and the flow of fuel provides the kinetic energy.

As fuel deteriorates, clusters of fuel components break down and residue begins to accumulate, resulting in dark, hazy fuel with poor combustibility. The increase in size and mass of the fuel breakdown products lead to clogged filters and the build up of tank sludge. The AXI Fuel Conditioner dissolves the clusters, stabilizes the fuel, and eliminates tank sludge. The results are Clear & Bright Fuel, improved filterability, optimal combustion and clean fuel systems. The process of how the AXI Fuel Conditioner makes clear, bright and more combustible fuel as well as restoring degraded fuel and eliminating the effects of microbial contamination is compelling. As the AXI Fuel Conditioner does not filter the fuel, but treats it as it passes through the unit, there is seldom any reason to suspect that a restriction is in the AXI Fuel Conditioner. But you can remove the face plate, remove the magnet and wipe it off with a shop rag and replace the filter and face plate. A spare parts kit for the AXI Fuel Conditioner includes a new face panel O-Ring and replacement screws to fasten the face plate.

Implement a Fuel Management Protocol

Cleaning your fuel tank should not be something that is done when someone happens to thinks about it, resulting in the treatment occurs at irregular intervals. Formulate a plan for keeping your fuel tank clean and your fuel in optimal condition, and then follow the plan.

There are many variables to consider in putting together a good plan, such as the use of the fuel being stored, how often the tank is drawn down and fuel is added to replenish the fuel level, do you have high confidence that the fuel you receive is good fuel, relatively free of water, or is it bio-diesel which is susceptible to having water mixed in with the fuel. Is the tank indoors in a temperature controlled environment or outside subject to wide temperature changes (increasing the possibility of water accumulating in the tank from condensation)? The climate conditions where you are located becomes a factor. If you are close to the ocean or in a humid climate, you would treat your fuel more often than if you are located in a dry, desert area.

Using the Right Fuel Additive

The AFC-705 Diesel Fuel Catalyst, and the AFC-710 Diesel Fuel Catalyst (for engines that require Tier 4 compliance) works "Hand and Glove" with the SFM-1080 Tank Cleaning System. Although the SFM-1080 can pump water and sludge from the tank bottom, and then recirculates the fuel repeatedly to gradually polish the fuel, making the diesel fuel "clear and bright" the way diesel fuel with optimal combustibility looks and performs, the debris and organic matter in the tank still sticks to the tank bottom, walls, baffles, and top, and residual water remains on the tank bottom.

Both AFC-705 and AFC-710 Diesel Fuel Catalyst dissolves the debris off the bottom and sides of the tank putting this debris up in suspension in the fuel so that as the fuel circulates through the SFM-1080, the debris is removed. Also, the AF-705 Diesel Fuel Catalyst (but not the AFC-710) has a chemical component that will emulsify the residual water up into the fuel. Then, as the fuel is circulated through the Secondary filter equipped with the WBS-3 Spin On water block filter element, the water is captured and the fuel loses the hazy look and becomes clear and bright.

In colder temperatures, AXI AFC-805 is an Anti-Gelling broad spectrum fuel additive that is ideal in cold weather applications where there is long term fuel storage. AFC-805 should be used as part of any preventative fuel maintenance program. It will break down and remove sludge, slime, and bio-fouling from tank walls and baffles that are difficult to access.

For a complete understanding of the steps involved in polishing diesel fuel, read the Cleaning a Fuel Tank Guide. All of our fuel management systems work essentially the same, only on different scales to address different sizes of storage capacity and management requirements, but this guide explains the process in detail using the TK-240.

Sample Tank Bottom

If a tank has a straight-line access to the bottom of the fuel tank from the fuel fill hole or through another inspection port, a length of PVC or similar material pipe, 1/2 inch in diameter, can be used like a soda straw to sample what is in the bottom of a tank. Cut the pipe to length to allow insertion of the pipe to the bottom while allowing your thumb to cover the exposed end of the pipe. With your thumb over the end, insert the pipe to the bottom of the tank, remove your thumb so what is at the very bottom will rush into the tube to the level of fuel in the tank. Again place your thumb over the end of the pipe and extract the pipe, maintaining the liquid and other materials inside the tube. Place an empty clear plastic 2 liter soft drink bottle upright in the bottom of a empty 5-gallon bucket. Direct the end of the tube into the drink bottle (any spilled liquid will be caught inside the five gallon bucket). Perform this action several times. Allow the contents of the bottle to settle (ideally overnight) and inspect the materials in the bottom of the drink bottle. Any debris or water should be apparent.

If your tank is larger and using a tube to recover fuel, water or other debris from the bottom of the tank is not possible, you can use a Tank Sample (TS) Fluid Sampler. You can take 4 oz., 8 oz, or 16 oz. samples using the AXI Tank Sampler or you can use a hand-held Sample Pump (at bottom of the AXI Tank Sampler page) to remove a sample, as described on the Tank Sampler page.

Ongoing Vigilance in Keeping Water Out of the Tank

Water in the tank is often at the heart of having fuel problems. Water can get into the tank with a load of fuel, it can be from rain water entering the tank when the cap is not replaced or is left loose, and it can be drawn in as fuel is used from a tank as moisture in the air condenses and accumulates.

In some climates, you should check for water in your tank each month. In some locations where fuel quality from the supplier is suspect, it is smart to use Kolor Kut Water Finding Paste, or a similar product, to check for water after each time you take on fuel. Water may be mixed in with the fuel when it is put into your tank. If possible, allow 48 hours for the fuel to settle and the water to separate from the fuel and accumulate on the bottom of the tank. Then place some Kolor Kut Water Finding Paste on the bottom 4 to 6 inches of a rod or length of rigid PVC tubing and stick it to the bottom of the tank. The paste will change colors if it touches water and indicate if any water, and how much water, has accumulated in the bottom of your tank.

If water in the tank bottom is a problem, consider taking one further step to preventing problems in the future by utilizing the Water Eliminator. This handy product contains crystals that absorb water, but not fuel, and contains the water until removal and proper disposal, minimizing the chance to water being a habitat for future microbial contamination and for water to be picked up in the fuel and causing damage to engine components.
